Is it normal for a 10 year old to be arrogant and act like they know everything. I know everyone can be this way from time to time, but its everything he talks about. I try to correct him and just give up because he will not listen to me because he has his mind set. I try to pick my battles so that the little things just slide by. I am just wondering if this is just a stage or if i have to take some kind of action to correct this?
